“…With similar goals, a shaking table test on a three-bay single story frame with two ductile and two nonductile columns was undertaken at the National Centre for Research on Earthquake Engineering (NCREE) in Taiwan in 2005 [2]. Kabeyasawa et al [3] and Shirai et al [4] have investigated the seismic response up to the stage of collapse for full-scale reinforced concrete buildings on the E-Defense shaking table in Japan. Testing a third-scale planar, three-story reinforced concrete frame, Ghannoum [5] studied the dynamic collapse behavior of frames with ductile and nonductile columns.…”

SUMMARYThe current paper presents nonlinear dynamic analyses that simulate shaking table tests performed on a four-column reinforced concrete frame described in a companion paper. The frame consists of two ductile and two nonductile columns interconnected by a stiff beam. In order to validate existing analytical models for nonductile concrete columns, a blind comparison of the test data and results of the analysis is performed. The analysis adequately captures the drift response and correctly detects collapse of the structure; however, strength degradation due to cover spalling is exaggerated in the analytical model. Refinement of the analysis by changing the concrete cover model results in an excellent agreement between the test data and analysis results at the initiation of shear failure and collapse of the frame. The experimental data are further compared with lumped-plasticity nonlinear models used in engineering practice. The results suggest that the sudden strength degradation used in ASCE/SEI 41-06 results in an exaggerated estimate of the displacement demands. It is also observed that ignoring the strength degradation, using an elastic-perfectly-plastic model, provides a good estimate of the displacement demands when strength degradation is not severe.

“…Numerous experimental studies, including static and shaking table tests, have been conducted. These studies can be classified into two categories: at the component level [Beres et al, 1996;Ghannoum and Moehle, 2012a;Elsouri and Harajli, 2013] and at the structural system level [Kabeyasawa et al, 2007;Wu et al, 2009;Moaveni et al, 2010;Panagiotou et al, 2011]. Among these, experimental studies of the overall structures are generally regarded as the most reliable method of investigation.…”

A thorough investigation of earthquake-induced collapse of reinforced concrete frames is presented. The inherent correlation between the nonlinear behavior of key components and the collapse mechanism of overall frame is examined through concurrent collapse tests of both frame and key components. Important issues in the component models are investigated through calibration against experiments, leading to a comprehensive structural system model. Both test and simulation indicate that the seismic performance are predominately governed by the key columns, whereas the energy dissipation capacity is somewhat affected by the joints. This study offers systematic experimental data and numerical models for future collapse assessments.

“…In 2006, Wu et al [7] carried out a 1:3 scaled shaking table collapse test of a one-story, single-bay and three-span RC frame structure. In 2007, a full-scale collapse test of a three-story RC structure with a flexible foundation was performed by Toshikazu et al [8] on the E-Defense shake table. In the following year, a similar test of a four-story steel frame structure was conducted by Yamada and his colleagues [9,10] and a progressive collapse test of a four-span three-story RC plane frame was conducted by Yi et al [11].…”

Research on earthquake-induced collapse simulation has a great practical significance for super-tall buildings. Although mega-braced frame-core tube buildings are one of the common high-rise structural systems in high seismic intensity regions, the failure mode and collapse mechanism of such a building under earthquake events are rarely studied. This paper thus aims to investigate the collapse behavior of a super-tall mega-braced frame-core tube building (H = 550 m) to be built in China in the high risk seismic zone with the maximum spectral acceleration of 0.9 g (g represents the gravity acceleration). A finite element (FE) model of this building is constructed based on the fiber-beam and multi-layer shell models. The dynamic characteristics of the building are analyzed and the earthquake-induced collapse simulation is performed. Finally, the failure mode and mechanism of earthquake-induced collapse are discussed in some detail. This study will serve as a reference for the collapse-resistance design of super-tall buildings of similar type.
